foki 0.5x^2-2x-2

Lösung

foki

0.5 x^{2} - 2 x - 2

Lösung

(2, - 3.5)

Schritte zur Lösung

Rewrite

y = 0.5 x^{2} - 2 x - 2

in the standard form

4 \cdot 0.5 (y - (- 4)) = (x - 2)^{2}

(h, k) = (2, - 4), p = 0.5

Parabola is symmetric around the y-axis and so the focus lies a distance

p

from the center

(2, - 4)

along the y-axis

(2, - 4 + p)

= (2, - 4 + 0.5)
